Definitions
- the present invention relates to a waterproof membrane in particular a waterproof membrane for use as a watertight barrier between or external to building components, the same membrane being furnished with protrusions or studs which function as distance pieces to ensure, for example, either ventilation or drainage along the membrane.
- a waterproof membrane in particular a waterproof membrane for use as a watertight barrier between or external to building components, the same membrane being furnished with protrusions or studs which function as distance pieces to ensure, for example, either ventilation or drainage along the membrane.
- Such membranes often are produced from plastics, e.g. polyolefines.
- Watertight membranes of this type are used horizontally or vertically along building costructions in order to prevent the ingress of dampness and at the same time to achieve ventilation and/or drainage on one of the membranes surfaces.
- DE 3127265 and DE 4004901 can be referred to as related and already known membranes. Both of these known solutions refer to double membrane foils or sheets which provide a watertight barrier and at the same time allow ventilation and/ or drainage since they are provided with protrusions or studs.
- Existing membranes or foils incorporating formed protrusions or studs in order to create a ventilation/ drainage cavity have several disadvantages.
- the purpose of the present invention is to provide a watertight membrane for building purposes which gives good ventilation and drainage in all directions and which at the same time can be folded in all the likely directions in a simple and safe fashion.
- the present product is a membrane which has both studs and preformed folding channels which can also function as drainage channels but which are present in the membrane in at least two crossing directions and where the studs have a size and/or shape which allows some of the folding channels in each crossing direction to reaiain unaffected by the studs.
- the membrane although including studs, can nevertheless be folded round corners without breaking the watertight surface. Since two sets of right angled folding folding lines crossing each other at 45 degrees are incorporated in the membrane it is possible to fold the same membrane into corners where three walls stand at right angles to each other without cutting or producing cracks.
- Fig. 1 shows one form of a membrane in accordance with the present invention seen from above
- Fig. 2 shows the membrane from Fig.l seen from the side
- Fig. 3 shows another form of the membrane seen from above
- Fig. 4 shows the membrane according to Fig. 3 seen from the side
- Fig. 5 shows a further form of the mnembrane according to the present invention
- Fig. 6 shows the membrane according to Fig. 5 seen from the side
- Fig. 7 shows yet another form of the membrane according to the present invention seen from above.
- Fig. 8 shows finally a form where the studs are small enough to find room between the folding lines without disturbing any of these. It should be noticed that the mutual relationship in size between the width of the folding lines or channels and the studs need not necessarily be as shown in the figure. This also applies to the height of the studs in relation to their size.
- Fig. 1 we see a typical membrane, in accordance with the present invention, seen from above.
- the membrane 1 is furnished with crossing sets of folding indentations 2,3,4,5.
- These folding indentations 2,3,4,5 are shown in the figure in the form of two sets of folding indentations, the one set consisting of horizontal 2 and vertical 3 indentations whilst the other set consists of the diagonal 4 indentations and, at right angles to these, the diagonal folding indentations 5.
- the two right angled sets of folding indentations cross each other at 45 degrees.
- the individual folding lines may be formed by pressing to produce a weakened line but preferably by forming an indentation or channel in the membrane by pressing, rolling or by some other method.
- the section of these folding indentations may be rounded or have another profile for example a sharp fold.
- the product is not limited to having two right angled sets of folding indentations such as shown in these examples but can, particularly if the membrane is to be used for a special purpose, be formed so that the foiding indentations cross each other at other angles.
- the only requirement is that there are present multiple folding indentations or channels which cross each other in a predetermined fashion. Protruding or recessed studs 6,7,8,9 are placed in the pattern of folding indentations.
- Fig.l shows a membrane where the studs lie regularly in the folding pattern, are square and bounded by some of the diagonal folding indentations 4 and 5. It is important to note that the studs 6,7,8,9 are so placed along the same horizontal, vertical and diagonal folding indentations that there remain indentations in these same three directions without such studs.
- the studs greatly reduce the flexi- bility of the membrane along the folding indentations covered by studs.
- the membrane will only be easy to fold along the lines marked with a star whilst unstarred folding lines will be stiffened by the stud formation.
- the idea of the invention is that studs shall be so placed in the pattern of folding indentations that some of these in each of the horizontal, vertical and diagonal directions shall remain unaffected by the stiffening resulting from tha positioning of the studs.
- Fig.2 shows a section through the membrane shown, viewed from above, in Fig.l.
- the membrane is shown here with folding lines in the form of semi-circular indentations in the otherwise smooth membrane whilst the studs are shown as large relief formed protrusions in the membrane in the opposite direction.
- the folding lines 2,3,4,5 as well as the studs 6,7,8,9 can be formed in the same or the opposite surface of the membrane. Since the studs 6,7; as mentioned above coincide with the boundary line along some of the folding indentations the walls of these studs 6,7 will, in this arrangement, go right through to the surface of the membrane. This is important for many applications since the stud walls will be stiff and will resist deformation under load. Placed between two building boards such a membrane will not give way under normal loadings.
- Figs. 3 and 4 show another solution where the studs are different in number and size and are placed parallel to the horizontal and vertical folding indentations Similarly, as can be seen from Fig.4 the height of the studs is relatively higher than the solution shown in Figs.l and 2. Looking more closely at Fig.3 it can be seen that only every other of the folding indentations i ⁇ unaffected by the stiffening brought about by the studs and their positioning. This membrane will therefore be less flexible than the membrane according to Figs.l and 2 as far as fitting round angles and into corners. On the other hand the membrane according to Figs.3 and 4 will be more resistant to compression before the studs are deformed.
- Figs.5 and 6 show a further solution where the flexibility of the membrane is retained in every other folding line in every direction but where the protruding or recessed studs are of cylindrical shape or more correctly have the shape of cut-off cones.
- the function in other respects will be as for the membrane in Figs.1-4.
- studs that have a pyramid shape at the point where they meet the plane of the membrane. In this way each wall of each stud passes directly into a folding channel. The smaller part of the stud can nevertheless have the form of a cut off cone.
- the studs can be described as having a "pyramid foot" and a "conical top”.
- FIG.7 a version of the membrane with larger studs is shown in Fig.7 where only studs 6 and 7 are shown in their entirety. In this case flexibility is only retained in one of three folding lines horizontally and vertically and in only one of six folding lines in both diagonal directions. This version can nevertheless have advantages in some applications.
- the most flexible form of the membrane is that where the studs are so small and have such a shape that they do not touch any of the folding lines or indentations at all but are placed between these. Two such variations are shown in Fig.8. In this case full flexibility is maintained also when compared with a membrane without studs but where the advantage of better ventilation and draining is achieved compared with a membrane without such studs. How frequently and where in the pattern of the membrane the studs should be placed depends first and foremost on which resistance to compression is desired.
- the membrane can be used in many different ways. For example it can frequently be advantageously employed where a membrane is needed between a concrete sole which is to be cast on an existing surface.
- the studs will be filled with the casting material for example concrete and when this has set the whole con ⁇ struction will resist compression whilst drainage channels and a ventilated interspace will be found as a net stretching in all directions over the area where the membrane has been employed.
- the direction of production can be along or parallel with the folding indentations 2, those designated 3; or parallel with those designated 4 or 5.
- the stud patterns it can be an advantage to let the production direction run along one of the diagonals in Fig.3. This will namely lead to an advantageous result in corner areas in that the studs in the folded area will fit together and "lock" the folding pattern in such corners.
